Treatment of the complex CPh)=CHPh>Cl(CO)(PPh3)2> (1) with one equivalent of CNR (R = tBu, C6H3Me2-2,6) gives CPh)=CHPh>Cl(CNR)(CO)(PPh3)2>.Addition of a further equivalent of isonitrile and PF6 leads to the salts CPh)=(CHPh>Cl(CNR)2(CO)(PPh3)2>PF6 and the mixed species CPh)=CHPh>(CO)(CNtBu)(CNC6H3Me2-2,6)(PPh3)2>PF6.The related CPh)=CHPh>(CNtBu)(CO)2(PPh3)2>PF6 is obtained by successive treatment of with diphenylbutadiyne, hexafluorophosphoric acid and isonitrile or of 1 with carbon monoxide, AgPF6, and CNtBu.
